FIELD: construction.SUBSTANCE: fibre-reinforced concrete pile formed by cylindrical shell with self-opening low end with openings on the lateral surface and injector with two tampons which is arranged in the cylindrical shell. Openings on the lateral surfaces of the shell are closed in the starting position with sliding shutters, secured on the shell surface by means of hinges and flexible high-strength couplings, limiting the sliding shutter opening. The internal cavity of the shell is filled with fibre-reinforced concrete under pressure through injector with two tampons and two tubes, thus opening the sliding shutters, the maximum opening of which is limited by flexible couplings, as a result cantilever beams are formed from fibre-reinforced concrete on the outer shell surface, reinforced for sensing the normal stresses by sliding shutters and flexible coupling, as well as reinforced fibres in fibre-reinforced fillers for perceiving the shear stresses.EFFECT: increase of structural strength, reduction of materials consumption.1 dwg |
